Cooling Tips?, Can we keep our engines cool? Options

[tiim5]

The recent heat wave in the bay area caused me to wonder if there are methods to 'cool' or otherwise lower the temperature of our engines while we are driving?

I recall an article in Hot Rod magazine years ago, suggesting coasting in neutral,
preferably downhill, as a method to cool a V8 engine. The engine at idle slows the pumping of coolant allowing more time to cool in the radiator. When you would put it back in gear the colder coolant would enter the block and the temperature drop was noticable.
I assume at idle our engines fans are least efficient but at higher rpm more air is moved but operating temp should also increase making this a wash?

Is there anything one can do to get the temp to drop? Is driving at a constant speed, 70 mph for example better than varying speeds?

If the engine gets hot is there any way to cool it down while driving?

Thanks

Going downhill is not really a practical way to cool the engine. While it does work, big downhills are usually hard to come by whenever your engine is running hot. :-)

The only way my engine cools off is to slow down. The faster I drive, the higher the temps go. So slow down to 55-60 or so and it should cool down. Maybe slowing to 50 and putting it in 4th gear might help even more (higher rpm's provide more cooling air), but I've never needed to try that.

But the motor cools pretty quickly when you shut it down. So taking a 7-11 break is another way to go.
